Procurement Notes

Verify the manufacturer designation carefully, as the QT216S series appears associated with both TXC Corporation and QST in public listings. Confirm that the specific part number QT216S-30.000MAAJ-T matches the required 30 MHz frequency, ±30 ppm stability, and 18 pF load capacitance. Ensure the package type corresponds to the 2.0x1.6mm SMD footprint and that the supply chain source provides valid documentation for the AEC-Q200 qualification status if automotive application is intended.

Selection Notes

Select this component when a 30 MHz fundamental frequency crystal is required with tight ±30 ppm stability constraints. The 18 pF load capacitance must match the host circuit's design specifications. Consider the 2.0x1.6mm package size for board space limitations. Verify compatibility with the target application's temperature range and vibration requirements, particularly if deploying in automotive or industrial environments where AEC-Q200 certification is relevant.

Part Context

The QT216S series represents a line of surface-mount crystals designed for general-purpose timing applications. This specific model operates at 30 MHz, distinguishing it from other frequencies within the same family such as 25 MHz or 31.125 MHz variants. The series supports various load capacitances and stability grades, allowing designers to choose components based on specific system precision needs and physical layout constraints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Designers should consult official distributor databases for cross-reference information. Ensure any replacement maintains the 30 MHz frequency, 18 pF load capacitance, and compatible package dimensions to preserve circuit functionality.
